So my wife's best friend has always been friendly to me but the last few times we've hung out she's done some weird things that make me think she may be flirting or trying to come on to me... For the record, I dig my submissive wife and am not trying to fuck around... and this is one of her best friends so I really don't want to cause any issues if I am misinterpreting this.

We're all in our early 30s and I got a decent career with nice house, cars and money in the bank. My wife and her friend grew up together and are super close. The friend is an artsy type no real job and has a fiance herself but he is a bipolar scumbag that has cheated on her before (also broke as shit, can't even afford to get married she says)...

She was always just conversational before but basically the past few times we've hungout she has acted differently. Like I noticed she is wearing much more revealing and lowcut tops when we hangout and will often lean down when talking to me so all her cleavage is showing or walk into the room not wearing a bra... Another time we were all out drinking and numerous times she was grabbing my arm with both hands every time she talked to me, which she never did before, then at the end of the night she tried really hard to convince my wife to let her sit in the middle of the backseat between us, which my wife seemed to think was weird cuz she said something like "I know u just wanna be up close to my hubby"... Whole car ride home friend is leaning into me literally pushing her boob into my arm whole time. Also some indicators like catching her staring at me or blushing when I hold eye contact too long. Shes also been giving compliments on my wife's looks and made a comment about wanting to kiss her.

I don't know her that well maybe hung out less than 10 times over the years but from some of these bahaviors I am thinking she might have a crush on me or is possibly trying to compete with my gf in some way, idk... Maybe even a threesome (I wish but wife would never). I may just be reading too much into it but wanted some 'advice' on if I am on if I'm reading this right or not and how I should handle this going forward.

Thanks bros.
